This is an idea I have been playing with for later in my timeline of a world without Christianity by way of a more consolidated and organized Bosporan Kingdom. What do you guys think the implications might be, though? Is the idea of a Greek state on the Dnieper feasible, in your minds? If so, will it inevitably get gobbled up by steppe nomads, or might it retain its character? If it retains its character, can it expand further north?
